If you can get the meter case apart, you'll find a small screw that tensions the meter movement bearing.? Back that out 1/8 of a turn, tap the needle and see if that freed it up.? That worked 100%

Picked up a very nice, cosmetically near-perfect RV4-C to go with the TR4CW-RIT; been wanting a nice one.? I expect it was cheap because it was unstable when tuned. Easy fix.? Shoot the MODE switch

Todays net we had 39 check-ins under excellent band conditions. Next week will be Bill W9MXQ doing the net. Here's the Drake equipment used to check-in today. TWINS = 12 TR3 = 4 TR4(x) = 9 TR5 =
